TRAP.

SPECIFICATIONforming part of Letters Patent No. 746,893, dated December15, 1903.

Application led November 20, 1902. Serial No. 132,174. (No model.)

-To all whom t may concern.-

Be it known that I, CHARLES WALDREN STANTON, a citizen of the UnitedStates, residing at Mobile, in the county of Mobile and State ofAlabama, have invented new and useform of an apparatus or structure forWhichit is applicable, and, further, aims to construct a trap whichshall be simple in construction, durable, cliicient in its use, andcomparatively inexpensive to manufacture.

To this end the invention consists of the novel combination andarrangement of parte hereinafter more specifically described,illustrated in the accompanying drawing, and particularly pointed out inthe claim hereunto appended.

In describing the invention in detail reference is had to theaccompanying drawing, which is a sectional elevation of the trap.

Referring to the drawing by reference characters, the trap isconstructed of a closed receptacle 1, formed of two sections, the lowerof which is cylindrical in contour and having a closed bottom and anopen top, and the npper of which is semispherical in contour andconnected at its lower end to the top of the lowersection.Thesemispherical-shapedsection of the receptacle 1 is provided with anopening 2 in the top, communicating with a gas-takeoff pipe 3, providedwith a cut-od 4. The upper section of the receptacle is further formedwith an opening 5, communicating with a filling-pipe 6, having a cut-off7. The pipe 6 is used for filling the receptacle Vl with a suitablequantity of a liquid sealing The lower section of the receptacle l, nearthe top thereof, has an opening 9, communicating with an overliow-pipe10, arranged above the level of the sealing medium 8. Below this pipe 10the lower section of the receptacle 1 is further provided with an,opening closed by means of a door or cover l1.

Ved to permit of access being had to the receptacle, so it can becleaned. Near the bottom of the lower Vsection of the receptacle 1,opposite the door or cover 11, is the substantially L-shaped entrance orinlet pipe l2,which communicates with the interior of the trap and isadapted to feed to the trap the products of condensation, uncondensedgases, or other matters when'the trap is in communication with anapparatus or other structure, or, rather, when the trap is connected upfor use.

The trap operates as follows: The sealing medium 8 is supplied theretoand the entrance or inlet pipe 12 placed in communication'with anapparatus or other structure as occasion requires. As the entrance orinlet pipe 12 extends into the sealing medium, it will be evident thatthe latter will prevent back atmospheric pressure to the apparatus orstructure with which the trap is in communication. The products ofcondensation, uncondensed gases, or other matters as they enter the trapcause the sealing medium to overflow through the pipe 10 and thecondensed products or other liquid matters assist in acting as a seal toprevent back atmospheric pressure.` lf all of the sealing medium 8 isdischarged from the trap, the products of condensation or other liquidmatters then act as a seal, these products or other liquid matters alsooverflowing when they reach a certain level. The overliow-pipe isarranged at such a distance above the entrance or inlet pipe 12 as toretain in the trap a suitable quantity of the sealing medium or productsof condensation or other matters at all times in the trap. The gases orvapors which are supplied to the trapthrough theinlet or pipe 12 andwhich pass up through the seal in the trap exhaust themselves throughthe overflow-pipe 10, as Well as through the take-off pipe 3, when thecock 4 is open.

From the foregoing construction of trap it will be evident that apermanent seal is formed therein to,prevent back atmospheric pressure.The door or cover 11 when open will also permit of the discharge of theseal- IOO ing medium or the products of condensation or other matterswhich do not overflow from the receptacle by means of the pipe l0.

It is thought the many advantages of a trap constructed in accordancewith the foregoing` description, taken in connection with theaccompanying drawing, can be readily understood, and it will furthermorebe evident that minor changes in the details of construction can be madewithout departing from the general spirit of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

ln a trap, a receptacle formed of two sections the upper of which issemispherical in contour and the lower of which is cylindrical incontour, each of said sections provided with a pair of openings, a doorfor closing one of the openings of the lower section, au overflow-pipecommunicating with the other opening in the lower section, a take-0Epipe communicating with one of the openings of the upper section andprovided with a cutoff, a filling-pipe communicating with the otheropening of the upper section and provided With a cut-off, and anL-shaped inletpipe projecting in said lower section near the bottomthereof, said receptacle adapted to contain a liquid to form a seal,substantially as herein shown and described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
